The listing does not say ProS, but if you look at the photo of the side up close, at least the body is. I might want to make sure that it has a ProS back as well. It has two lenses and a prism. Pretty nice set up.

I keep telling my friend hes not going to get 600 for it. Maybe 500 since its in immaculate condition (10-20 rolls put through, and that might be pushing it), but I've seen the exact same kit(even w.o the lens) on ebay for $400-500.

Well - not so fast: a pristine ProS is very likely to fetch that much. And it would be worth every penny to a person who cares about the cosmetic condition of his gear (and many people do). The one here on APUG is an exceptional deal (as in: I woud be buying it right now if I had the cash!). Most of the ones that go for that much on eB@y are not as nice, usually not ProS's and often come with a 220 back (a dirty trick I noticed with a lot of them that advertise "2 backs!", 220 film is not the easiest film to get your hands on...).
Your friend may very well get his asking price due to the condition - but for someone looking to get a "user" in good mechanical condition, yes, there are better deals out there. But few if any as good as the one on our classifieds.

Two monthe ago I bought proS starter kit (body, 120 magazine, WLF and 127/3.8) for about 500EUR. Keep in mind I am in Europe, where proces are higher than is USA, and another reason for buying at that price is I know previous user/seller and I know man who maintained that equipment. And it comes in great working and cosmetic condition. Want to say I was ready to pay more for reliable source, instead to try luck on net, and maybe to be in need to pay for additional CLA or even repairing.
